The network rendering, Irradience maps, transposer built in, matchmoving etc, and the generous introductory discounts(30%) for PC club members on top of the reg. discount had me seriously considering the upgrade to Pro. But the cost of filling my gas tank due to the recent oil price boost, and other expenses will rule it out for me right now. Oh well, Carrara5 standard is a blast, and there's quite a bit that I can do with it now. I haven't come near to exhausting its possibilities yet.
